AMD Ryzen 9 5980HS Cezanne Review: Ryzen 5000 Mobile Tested - AnandTech

AMD announced its new Ryzen 5000 Mobile processor family at the start of the year, with processors from 15W to 45W+ in the pipeline, and the first mobile systems coming to market in February.

AMD sent us a peak example of Ryzen 5000 Mobile for today’s review, the 35W Ryzen 9 5980HS, as contained in the ASUS ROG Flow X13.

For those that didn’t catch the original announcement a couple of weeks ago, here is a recap of the Ryzen 5000 Mobile family as well as the key points from the announcement.

The Ryzen 5000 Mobile processor series is an upgrade over last year’s Ryzen 4000 Mobile processor series.

The Ryzen 5000 Mobile family is split into two broad product ranges, but both ranges use the same underlying silicon.

When HS was introduced last year with Ryzen 4000 Mobile, it was an AMD-OEM partnership-only co-designed product requiring AMD approval in order to have access to them.

There is some slight deviation from the regular H-series, in that there is no Ryzen 9 standard ‘H’ processor.

AMD is advertising the Ryzen 9 5980HS as the best processor for portable gaming performance, while the Ryzen 9 5980HX is ‘the best mobile processor for gaming’.

The traditional 15 W processors, used for ultra-thin and light portable notebooks, form part of the Ryzen 5000 Mobile U-series.

Based on a number of enhancements to the silicon design, AMD is claiming a +2hr battery life from a simple processor swap from Ryzen 4000 to Ryzen 5000, even if everything else in the chassis is the same.

Other OEMs however, particularly for low cost designs or perhaps education models, can freely change the processor from old to new with only a firmware update, as both Ryzen 4000 and Ryzen 5000 are pin compatible.

Overall AMD is claiming 150+ designs with Ryzen 5000 Mobile so far, a significant step up from the 100 designs on Ryzen 4000 Mobile.

Under the hood is that AMD Ryzen 9 5980HS processor, with eight Zen 3 cores and sixteen threads, with a 3.0 GHz base frequency and a 4.8 GHz single core turbo frequency, rated at 35 W.

ASUS says that they buy the best versions of the 5980HS for the Flow X13 to ensure the best performance and battery life.

Similar to the launch of Ryzen 4000 Mobile, the unit AMD has supplied us is their top of the line but most efficient H-series processor

We have no word on when those units will be in the market (we are told soon), however we have managed to secure an MSI Prestige 14 Evo which contains Intel’s best U-series processor (Core i7-1185G7) and allows for sustained performance at 35 W

But first, let us discuss the new features in Ryzen 5000 Mobile
